RESUMO
Objective To investigate the prevalence of nutritional risk (NRS2002) and malnutrition inhospitalized stroke patient and their nutritional intervention. Methods The stroke patients admitted to three de-partments of vascular neurology ward including cerebral hemorrhage, cerebral infarction and subarachnoid hemor-rhage in Beijing Tiantan Hospital from January 2018 to January 2019 were recruited using cluster sampling. Nutri-tional risk screening 2002 ( NRS 2002) was used to screen the nutritional risk of inpatients Malnutrition was as-sessed by criteria:(1) body mass index (BMI) <18. 5 kg/m2 with poorer general condition from January 2018 to January 2019;(2) Global leadership initiative on malnutrition ( GLIM) criteria were used except whole body muscle mass measurement from October 2018 to January 2019. The nutritional intervention for patients were closely observed during hospitalization. Results A total of 1532 patients were registered and1036 patients were included in the final analysis considering the inclusion and exclusion criteria. The prevalence of nutritional risk was 33. 0％ ( 342/1036) . The prevalence of malnutrition based on BMI and GLIM criteria was 0. 9％( 9/1036) and 2. 5％ (10/393) respectively. Among the 342 patients with nutritional risk, 112 patients received nutritional support therapy by tube feeding, but only 29 patients received nutritional support that met guideline standards. 81 patients received not standard nutritional support, and 2 patients received highly unregulated nutritional sup-port. No patients received sugar and electrolyte infusion, oral nutritional supplements ( ONS) , oral nutritional a-gents and compound nutrition intervention. The other 230 patients took hospital diet. Conclusion The prevalence of nutritional risk in hospitalized patients with cerebral hemorrhage, cerebral infarction or subarachnoid hemorrhage was high, and the prevalence of malnutrition was extremely low. There was a low proportion of nutri-tional support. High quality of large sample cohort studies will be conducted to show whether reasonable applica-tion of nutritional support therapy in patients with nutritional risk can improve patient outcome.
RESUMO
Objective Sharing and exploring the efficient development of scientific research management with peers in large tertiary general hospital.Methods This article took the whole process management of scientific research in our hospital during the past five years as example,analyzed and elaborated the quality control and related safeguarding measures.Results According to the comparison between 2012 and 2016,the number of SCI papers published,the number of National Natural Science Funding and other important indicators all have been increased significantly in our hospital.Conclusions The implementation of the whole process quality control management and security measures of scientific research helps hospital to achieve initial and efficient development in research management.
RESUMO
Objective To achieve the hospital's scientific research objectives during the 13th five-year plan period,we designed to know about the potential NSFC application capacity and existed problems in our hospital.Methods Using "Questionnaire Star" network investigation platform to design questionnaire and conduct data analysis.Results Respondents are divided into two groups,one was who intend to apply in next three years while the other would not.it is found that there are obvious differences between the publication of SCI,as well as the previous research project application and conducting experiences.Conclusions In order to improve the rate of NSFC application,the hospital scientific management workers can consider doing the following:Improve the number of SCI papers published from the perspective of helping to encourage and forcing pressure.Strive for financial support from all parties and build a central experimental platform to create conditions for basic experiments for clinical medical workers.Regular and in time training for NSFC application.Some pressure when necessary to promote the extension of low-level study.Pay more attention to the incentives of research performance at the department level.
RESUMO
Objective To investigate the characteristic changes of the metabolism products in the auditory cortex (transverse temporal gyrus)in patients with metabolic syndrome combined with sensorineural deafness using 1 H magnetic resonance spectroscopy (1 H-MRS),and to find out the early warning indicators of sensorineural deafness in patients with metabolic syndrome.Methods The pure tone audiometry (PTA)was performed in 142 pa-tients with metabolic syndrome (diagnosed by endocrinology department),and 15 healthy subjects as the control group.The patients were divided into four groups:the metabolic syndrome group;the metabolic syndrome group with unilateral,the bilateral deafness group,and the control group.Cerebral metabolism was studied by assessing the ratios of nitro-acetyl aspartate contrast to choline (NAA/Cho)as well as to creatine (NAA/Cr),myo-inosi-tol to creatine (mI/Cr)and choline to creatine (Cho/Cr)ratios in the auditory cortical separately in these groups. ROC curves were made for those metabolism markers to find the best diagnostic threshold.Results Significantly lower values of NAA/Cho ratio and higher values of Cho/Cr were observed in metabolic syndrome in the control group (P<0.05),Cho/Cr higher than those (P<0.05).NAA/Cho ratios in the injured and uninjured auditory cortex of MS with unilateral deafness were significantly lower than those in the control group (P<0.05).A self-comparison was made between the inj ured and uninj ured auditory cortex,the result showed that NAA/Cho ratio had significant differences.All of the metabolisms were tested by the curve of ROC.The area of NAA/Cho under the ROC curve was 81%,which had a higher accuracy.NAA/Cho equating to 1 .82 could be used as the boundary indi-cators between metabolic syndrome without deafness and with deafness groups.The areas of the other indicators un-der the ROC curve were <50%.Conclusion NAA/Cho may be the early warning marker of sensorineural deafness in patients with metabolic syndrome.

Objective To investigate the characteristic changes of the metabolism products in the auditory cortex (transverse temporal gyrus) in diabetes combined with nerve deafness using 1 H magnetic resonance spectros‐copy (1 H -MRS) ,and to discover the early warning indicator of nerve deafness in type 2 diabetes .Methods PTA was performed in 98 patients with type 2 diabetes (diagnosed by Endocrinology Department) ,and in 15 healthy sub‐jects in the control group .The patients were classified into four groups :the group of type 2 diabetes;type 2 diabe‐tes with unilateral and bilateral deafness ,and the normal control group .Cerebral metabolism was studied by assess‐ing the ratios of nitro -acetyl aspartate contrast to choline (NAA/Cho) as well as to creatine (NAA/Cr) ,myo-in‐ositol to creatine (mI/Cr) and choline to creatine (Cho/Cr) ratios in the auditory cortical separately in these groups . The Pearson correlation analysis was applied to determine blood glucose value with the nerve metabolites while the ROC curves were made for those metabolism markers to find the best diagnostic threshold .Results NAA/Cr and NAA/Cho were negatively correlated with AHI index and Cho/Cr ,mI/Cr was positively correlated with blood glu‐cose value .Significantly lower values of NAA/Cho ratio were found in patients'(diabetes without deafness) auditory cortex compared with 15 age-matched control subjects (P<0 .05) .NAA/Cr and NAA/Cho ratio in diabetes with deafness were significantly lower than those in control group (P< 0 .05) ,Cho/Cr higher than those of in other groups (P<0 .05) .NAA/Cr and NAA/Cho ratio in injured and uninjured auditory cortex of diabetes with unilateral deafness were significantly lower than those of in control group (P<0 .05) ,then we made a self -comparison be‐tween the injured and uninjured auditory cortex ,finding that NAA/Cho ratio had a significant difference .All of the metabolisms were tested by the curve of ROC .The area of NAA/Cho under the ROC curve was 81% ,which had a higher accuracy .NAA/Cho equal to 1 .65 can be used as boundary indicators between diabetes without deafness and diabetes with deafness groups ,the areas of the remaining indicators under the ROC curve was<50% .Conclusion NAA/Cho may be the early warning marker of nerve deafness in type 2 diabetes .
